.40 S&W Ammo Tray

thingiverse

Simple ammo holders. 50-round or 25-round. All stack together neatly. You can stack one or two 25-round holders on top of the 50-round holder. They're slightly oversized for .40 caliber rounds, so they might work well for .45 caliber rounds too. I haven't tested it with a .45 round though. These aren't what you'll take to the shooting range. Designed to print fast and tidy up loose rounds in my safe quickly. If you need sturdier range holders, these aren't your best bet. But if you want lightweight holders that print quickly using minimal filament, these are your top choice.
